I've heard it said that, if you take a walk around Waikiki, it's only a matter of time until someone hands you a flyer of scantily clad women clutching handguns, overlaid with English and maybe Japanese text advertising one of the many local shooting ranges. The city's largest, the Royal Hawaiian Shooting Club, advertises instructors fluent in Japanese, which is also the default language of its website. For years, this peculiar Hawaiian industry has explicitly targeted Japanese tourists, drawing them away from beaches and resorts into shopping malls, to do things that are forbidden in their own country.

Almost no one in Japan owns a gun. Most kinds are illegal, with onerous restrictions on buying and maintaining the few that are allowed. With almost one privately-owned firearm per person, America's ownership rate is the highest in the world; tribal-conflict-torn Yemen is ranked second, with a rate about half of America's.

But what about the country at the other end of the spectrum? What is the role of guns in Japan, the developed world's least firearm-filled nation and perhaps its strictest controller? In 2008, the U.S. had over 12 thousand firearm-related homicides. All of Japan experienced only 11, fewer than were killed at the Aurora shooting alone. And that was a big year: 2006 saw an astounding two, and when that number jumped to 22 in 2007, it became a national scandal. By comparison, also in 2008, 587 Americans were killed just by guns that had discharged accidentally.

Japanese tourists who fire off a few rounds at the Royal Hawaiian Shooting Club would be breaking three separate laws back in Japan — one for holding a handgun, one for possessing unlicensed bullets, and another violation for firing them — the first of which alone is punishable by one to ten years in jail. Handguns are forbidden absolutely. Small-caliber rifles have been illegal to buy, sell, or transfer since 1971. Anyone who owned a rifle before then is allowed to keep it, but their heirs are required to turn it over to the police once the owner dies. Even the country's infamous mafia-like Yakuza tend to forgo guns; the few exceptions tend to become big national news stories.

The only guns that Japanese citizens can legally buy and use are shotguns and air rifles, and it's not easy to do. The process is detailed in David Kopel's landmark study on Japanese gun control, published in the 1993 Asia Pacific Law Review, still cited as current. (Kopel, no left-wing loony, is a member of the National Rifle Association and once wrote in National Review that looser gun control laws could have stopped Adolf Hitler.)
